Patented Apr. 29, 1930 'fr ne aus GEORGE I-I. DAWSON, OF OAMBRIDQE, MASSACHUSETTS) ASSIGNR, BY MESNE AS- SIGNMENTS, TO REMINGTGN RAND TNC.. F NEW YQRK, N. Y.. A CGRPORATTON 0F DELAWARE CARD INDEX Application led. November 16, 1925.

This invention relates to a card index of the overlapping type in which each card has an exposed edge for a caption and concerns itself primarily with transparent means for covering and protecting the exposed margins of the cards.

It has heretofore been proposed to apply, as by gluing or pasting, a transparent strip to the rear of the lower margin of each card for protecting the caption on the nether card. This structure7 however, proved unsatisfactory for various reasons among which may be mentioned the fact that in many cases, a card is used but a short time, and when it is discarded the transparent strip has to be discarded therewith. Tt was also more or less diflicult to properly aline the transparent strip and card.

ln order to overcome these objections.,l l have provided means separate from the cards for supportingthe transparent protector strips, so that the same will not have to be destroyed when a card is discarded and which will always be properly alined and which will facilitate the use of the index.

The invention comprises the novel structure and combinations hereinafter described and more particularly pointed out and dened in the appended claims.

ln the accompanyingr drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different- Views.

@n the drawings:

Figure l is an elevational view of a pair of card holders with their supported cards involving this invention;

Fig. 2 is an enlarged sectional view upon the line lI-TI of Figure l, and

Fig. 3 is a'n elevational view of the card holder with the card detached.

As shown on the drawings:

As illustrative of this invention, there is shown a card holder comprising a supporting member l, adapted to support the cards in the guide channels of a tray as is well known in the art. A fibrous hinge 2 made of stiff paper or the like is secured upon the supporting` member l. This hinge member is provided Serial No. 69,357.

with a pair of longitudinally weakened sections 3 formed by a series of suitable apertures. and a pair of eyeleted disks a one near each margin of the hinge member between sain weakened sections for supporting a card 5 which has lateral notches for engaging the eyeleted studs upon which the disks 4 are secured.

Each hinge member extends a suitable distance below the supporting member l, and its lower margin is provided with a pair of similar recesses 6 of equal depth spaced a slicrt distance from the lateral Sides thereof. These recesses form a pair of edge tongues or flaps 7 and a central or intermediate tongue or flap 8 which determine the amount of overof a transparent protector strip 9 of celluloid or the like which is attached between the flaps 7 and 8; the flaps 7 lying on one side of the protector strip and the flap 8 lying upon the other side thereof with the upper edge of the strip abutting the tops of the recesses. Each transparent strip is preferably glued to the flaps 7 and 8 and depends a suiiicient distance below the card mounted upon its hinge member for covering and protecting the eX- posed margin of the nether card.

lt will be appreciated that on account of the equal depths of the recesses 6, they serve as guides to properly align each transparent strip in parallel relation with its hinge member, and also govern the amount of overlap of each hinge member and its transparent strip, so that the combined depth of all the hinge members and their transparent strips will be substantially the same. Further, the tongues or flaps 7 and 8:, since they embrace opposite sides of the transparent strip will also tend to prevent warping of the same.

These card carriers are designed to be sup ported in a tray, and the cards suspended therefrom are designed to lie in overlappi` relation as shown in Figure l. In referring to said ligure, it will be noted that the transparent strip on each hinge member depends below the card on such hinge member for covering and protecting the exposed edge of the nether card and as the cards are not combined with the transparent strips they may be readily removed and replaced by others without entailing any loss or waste oi the transparent protectors.

It will be appreciated that it the transparent strips were directly combined wi h he cards the labor and expense of puttin" parent strips upon replacement cai f; be considerable. Consequently y ing is elif/acted by this invention in addi a more desirable index.

I am aware that many changes n .Y made and numerous details of coi may be varied through a wide w1 depart-ing from the principles oi this invention and l therefore do not purpose limiting the patent granted thereon other-.vise than necessitated by the prior art.

l claim as my invention r l. In a card index system, a plurality of card holders, each comprising a spaoiAL f bar and an extended hinge member, said hinge member having pair ci parallel hinge oints, a cart removably mounted on sind hinge member between said hinge joints and a tr nsparent strip attached to said hinge member below said hinge joints.

2. In a card index system, a plurality ot card holders, means for spacing said card holders in overlapping offset relation, a plurality of cards mounted upon saio card holders, said card holders moruiting` said cards in overlapping relation with their lower margins exposed and a transparent protector strip secured to each card holder and depending below the card on each holder for protecting the exposed edge oi" the nether cart 3. In a card index system, a card holder, a card removably7 mounted upon said holder, and a transparent strip secured to said holder at the rear o and independent ot said card Lind depending` below the same for the purpose set forth.

4. A card carrier, comprising means for removably7 supporting a card and a transparent strip permanently attached to said supporting means and depending below said card for the purpose set forth.

5. A card holder comprising` a supporting bar and hinge member, a transparent strip attached to said hinge member and an index card removably attached to said hinge above said strip, said transparent strip extending beyond the iiree margin of said card.

6. A card holder comprising a hinge member having a transparent marginal portion and a card removably mounted upon said hinge member, said transparent marginal portion extending beyond said card for the purpose set forth.

7. In a card index system, a plurality of card holders, means for spacing said cards in overlapping offset relation, a plurality ot cards mounted upon said holders, said holders supporting said cards one in front of another with their lower margins exposed, each holder having a freely swingable hinge below the tree marginal portion of its respective holder means, and a transparent protector secured to said holder means between adjacent cards and covering the free marginal portion of the nether card, said cards being removable from said holder means.

9. In a card index system, a pair of card holders, means spacing said holders in offset overlapping relation, cards removably supported upon said holders and retained thereby in overlapping relation, and a transparent protector permanently attached to the foremost card holder beneath the card thereon and depending therebelow for covering the margin of the nether card.

In testimony whereof I have hereunto subscribed my name.
